Although weather does have a part in the reception here, and one local clue for the antenna I have hooked up to a HD 1080 PI 52" Samsung tv is if KRIS 6-1 does start to not come in or has less than three bars of signal strength on the tv menu / built in signal strength meter , I have received a fair number of stations that are well beyond the local reception maps. I do not have all of the call letters for all of the stations. I will not list the local Corpus Christi Stations.
I do have a four bay bow tie antenna, modified with four 4 gauge copper wire elements that are about four feet long, and are active elements with 300 OHM twin lead connecting them with the four bow ties that are tiered together in conjunction with the 4 gauge copper wire elements, with the signal fed into a GE 24 db gain amplifer, after going threw a 300 OHM to 75 OHM transformer.I have placed the antenna on top of a couple of chairs at the top of the stairs recently, as I have framing holding the copper still.

49-1 KPXB
now for the weird thing :the tuner registars 49-81, 49-82, 49-83,49-85,49 -87 GO!TV,49-88 Red Zone,49-90 Starz,49-91 Encore, 49 - 92Showtime, 49-93 Showtime, 49- 96 Airbox, but when I select these stations, the set does not respond to selecting the channel?!

67-1 KFXV - DT
67-1 KFTH- DT
67-2 KFXV
67-2 KXLN- SD

also analog 14 overiding local analog 14
analog 17 from Mexico
analog 11,12, 22 - all have been received in snowy color

I currently have a 24 " RCA LED 1080 PI tv set that seems to require a fairly large threshold signal to pick a station up, and have experimented with an antenna held together with alligator clips on top of the rug on the second floor, and have changed out that antenna with a twelve bay bow tie antenna with no amplifier. The antenna is aproximately nine feet long and mounted to the wall with screw in hooks above the door frame but just a couple of inches from the ceiling. The antenna is longer than the ceiling is high.

I have received a few stations on that set that may surprise a few people.
